这篇文章描述了如何使用 liquibase 从 maven 更新两个数据库： liquibase using maven with two databases 但是，当我在我的 pom.xml （包括在下面）中尝试完全相同的配置时，它不起作用。运行“mvn liquibase:update”时出现此错误：

The driver has not been specified either as a parameter or in a properties file.

在详细设置为 true 的情况下运行，我得到：

[INFO] Settings----------------------------
[INFO]     driver: null
[INFO]     url: null
[INFO]     username: null
[INFO]     password: null

所以看起来配置没有传递给liquibase。如果配置部分在执行之外它可以工作，但这会破坏具有多个执行的整个想法 - 您可能希望对不同的执行使用不同的配置。

谢谢，哈里

从 Mark 的评论中尝试“mvn process-resources”后更新。这是 mvn 更新两个数据库的输出。

您的构建是否需要一次更新 2 个数据库？另一种方法是使用 Maven 配置文件，如下所示：

mvn process-resources
mvn -Pdb2 process-resources

项目文件

|-- pom.xml
`-- src
    `-- main
        `-- resources
            |-- com
            |   `-- myspotontheweb
            |       `-- db
            |           `-- changelog
            |               |-- db-changelog-1.0.xml
            |               `-- db-changelog-master.xml
            `-- liquibase.properties

我更喜欢使用 Maven 的generate-resources阶段来创建一个 liquibase 属性文件。

pom.xml

最后包含两个配置文件，其中包含与两个数据库关联的属性。此解决方案可扩展到任意数量的数据库环境。

另一个需要注意的是，liquibase 使用了目标目录下的填充属性

            </activation>

                <liquibase.username>user</liquibase.username>

            </properties>
        </profile>
    </profiles>
</project>

liquibase.properties

这是使用特定环境的配置文件属性值填充的模板文件。

# Database credentials
url=${liquibase.url}
driver=${liquibase.driver}
username=${liquibase.username}
password=${liquibase.password}

# Liquibase changelog
changeLogFile=com/myspotontheweb/db/changelog/db-changelog-master.xml

更新

替代策略是直接运行插件，而不是将其集成到 Maven 生命周期中。

mkdir target
mvn liquibase:update
mvn -Pdb2 liquibase:update

您再次使用配置文件来控制属性设置。

pom.xml

不同之处在于插件设置由配置文件中设置的属性控制。不再在目标目录下创建用于在您的 jar 中运送的属性文件。
